This value is different than the per pixel Surface alpha. The first argument is the surface we're using. Remember: its a good idea to always set your pointers to NULL if they're not pointing to anything. it is an old game.... #1 Vicboss View Profile View Posts Jun 3, 2015 @ 4:48am Originally posted by UglyGeorge:im no expert at all, but is it possiable that your operating

Now that you know, the general consensus is to never use this. The alpha value is an integer from 0 to 255, 0 is fully transparent and 255 is fully opaque. Oh well. This function will temporarily lock and unlock the Surface as needed. :Parameters: `pos` : (int, int) X, Y coordinates of the pixel to write `color` : (int, int, int) or (int,

The clipping area is always restricted to the area of the Surface itself. It is a good idea to convert all Surfaces before they are blitted many times.

Proving the regularity of a certain language How much should I adjust the CR of encounters to compensate for PCs having very little GP? When blitting this Surface onto a destination, the pixels will be drawn slightly transparent. Mapped color values are not often used inside Pygame, but can be passed to most functions that require a Surface and a color. The new pixel format can be determined from another existing Surface.

Lentvorski, Jr." References: [pygame] Cannot blit to an OpenGL surface From: "Andrew P. Unlike the `convert` method, the pixel format for the new image will not be exactly the same as the requested source, but it will be optimized for fast alpha blitting to If hardware support is available, it will be used. :Parameters: `source` : `Surface` The source surface to copy from `destpost` : (int, int) or `Rect` Position to draw the source on Hot Network Questions Is there a single word for people who inhabit rural areas?

What's wierd is that the lock count jumps from 512 to 1024 when the application is focused and jumps back to 512 when unfocused, what could possibly change that? SDL subsystems are things like the video, audio, timers, etc that are the individual engine components used to make a game. Returns the bitmasks used to isolate each color in a mapped integer. See the Surface.lock() documentation for more details.

The fill will also be contained by the Surface clip area. How do I approach my boss to discuss this? Returns a new rectangle covering the entire surface. Now we have to update the screen using SDL_Flip() so that the screen surface we have in memory matches the one shown on the screen.

Getting and setting pixels one at a time is generally too slow to be used in a game or realtime situation. I am only using a single sprite in the whole application and its surface is only drawn to once with SDL_LoadBMP, and it returns that it was successful so it doesn't SDL_Delay() accepts time in milliseconds, or 1/1000 of a second. Get the offset position of a child subsurface inside of its top level parent Surface.

If the Surface is not a subsurface this will return (0, 0). :rtype: (int, int) ''' if not self._subsurface: return (0, 0) return self._subsurface.offsetx, self._subsurface.offsety def get_abs_offset(self): '''Find the absolute position This will replace the colors in the existing palette. This value is not needed for normal Pygame usage. :rtype: (int, int, int, int) ''' format = self._surf.format return format.Rmask, format.Gmask, format.Bmask, format.Amask def get_shifts(self): '''Get the bit shifts needed to The blitting will copy pixels from the source.

Textured quads are the 'recommended' way to do this, but you are correct with the powers of 2 setup. I'm not on my home computer or I would find the way to fix it. What does Billy Beane mean by "Yankees are paying half your salary"? The new Surface will have the same pixel formats, color palettes, and transparency settings as the original. :rtype: `Surface` ''' surf = self._surf self._prep() newsurf = SDL_ConvertSurface(surf, surf.format, surf.flags) self._unprep() return

Makes a duplicate copy of a Surface. Set the full palette for an 8bit Surface. So when you blit the message surface, it's going to blit it 180 pixels right, and 140 pixels down from the origin in the top left corner: SDL's coordinate system is All trademarks are property of their respective owners in the US and other countries.

If None is passed, the colorkey will be unset. If there was an error, loadedImage will be NULL. An example would be 'mysurf.get_rect(center=(100,100))' to create a rectangle for the Surface centered at a given position. :rtype: Rect ''' rect = pygame.rect.Rect(0, 0, self._surf.w, self._surf.h) for key, value in kwargs.items(): This value is not needed for normal Pygame usage. :rtype: int ''' return self._surf.pitch def get_masks(self): '''Get the bitmasks needed to convert between a color and a mapped integer.

Have to hit the archives for more, I can't remember more than that at the time. I'm pretty sure you can figure out what SCREEN_WIDTH and SCREEN_HEIGHT are. Otherwise, this argument is the depth, specified in bits per pixel. `flags` : int or None Otherwise, this argument is the flags for the new surface; a combination of SWSURFACE, HWSURFACE Targenor Visa allmän profil Skicka ett privat meddelande till Targenor Hitta fler inlägg av Targenor Hitta alla inlägg av Targenor i detta ämne Svara på ämne Svara Topp Dela Facebook Digg

Not the answer you're looking for? It was 5 bucks. If the image loaded fine, SDL_DisplayFormat() is called which creates a new version of "loadedImage" in the same format as the screen. SCREEN_BPP is the bits per-pixel.

The rect argument will limit the fill to a specific area. SDL Error: %s\n"m SDL_GetError() ); return false; } return true; } Thanks in advance! The issue i am having is when trying to blit the sprites surface, there it gives me the SDL error Surfaces must not be locked during blit which seemed reasonable so The Surface will always return a valid rectangle that will never be outside the bounds of the image.

And for more information check what is the returned value of SDL_BlitSurface(). Convert an mapped integer color into the RGB color components for this Surface. I just can't blit car on glyph –Thomas Ayoub Oct 15 '13 at 12:06 | show 4 more comments up vote 0 down vote accepted As MahamGM said, there was a When using default masks, alpha will always be ignored unless you pass SRCALPHA as a flag.

Returns the pixel shifts need to convert between each color and a mapped integer. The index should be a value from 0 to 255. You may be asking yourself "why aren't we freeing the screen surface?". If you run the program and the images don't show up or the window flashes for a second and you find in stderr.txt: Fatal signal: Segmentation Fault (SDL Parachute Deployed) It's

Should foreign words used in English be inflected for gender, number, and case according to the conventions of their source language? If None is passed, the colorkey will be unset.

That is what I need the software to do, I guess I will figure out another way to show the final grades. Does hiding TIN lines affect volume takeoffs?

Most surface types allow accessing the surface without using Cairo functions. If the surface doesn't support direct access, then this function does nothing. When using this value, note that the version of cairo at run-time may have additional status values defined than the value of this symbol at compile-time. (Since 1.10) cairo_status_to_string () const When the last call to cairo-surface-destroy decreases the reference count to zero, cairo will call cairo-surface-finish if it hasn't been ca...
